14 / 24 page 14 FN6599.1 May 13, 2009 SVI WIRE Protocol The SVI wire protocol is based on the I2C bus concept. Two wires (serial clock (SVC) and serial data (SVD)), carry information between the AMD processor (master) and VR controller (slave) on the bus. The master initiates and terminates SVI transactions and drives the clock, SVC, during a transaction. The AMD processor is always the master and the voltage regulators are the slaves. The slave receives the SVI transactions and acts accordingly. Mobile SVI wire protocol timing is based on high-speed mode I2C. See AMD Griffin (Family 11h) processor publications for additional details. TABLE 3.
